Engineering design is a systematic, intelligent process in which designers generate, evaluate, and specify concepts for devices, systems, or processes whose form and function achieve clients' objectives or users' needs while satisfying a specified set of constraints.

Using Computer-Aided Design (CAD) tools, engineers can create precise 2D and 3D models, simulate performance, and optimize designs before manufacturing. This approach reduces costs, improves quality, and accelerates the development process.

Modern engineering design embraces sustainability, innovation, and user-centered approaches to create solutions that are not only functional but also environmentally responsible and aesthetically pleasing.
